[Q]It is already well-known that one can unlock the fourth core of a triple core AMD Phenom II CPU. But during a test of the current ASRock A790GXH/128M motherboard at ocinside.de it was possible to unlock much more than this and that is a no April joke. The AMD Phenom II 710 X3 CPU became an Engineering Sample with four CPU cores, unlocked Vcore selection and unlocked multiplier ! All necessary BIOS settings for this modification are explained in the following AMD Phenom II unlock guide.[/Q]
